Rear Panel
SW1 Switch
The SW1 Programming, Monitoring, and Shutdown Select switch is an 8-position
piano DIP switch located on the power supply’s rear panel. See Figure 1.3. The SW1
switch enables you to choose:
•
Resistive programming of output voltage or current limit
•
Output voltage and current limit programming scales
•
Output voltage and current monitor scales
•
Remote shutdown circuit logic
•
Over temperature shutdown mode
